Many faces of CIA base bomber

US intelligence sources say a Jordanian double agent who attacked CIA operatives in Afghanistan last week, had provided high-quality intelligence leading to the deaths of several al-Qaeda leaders.

Hammam Khalil al-Balawi blew himself up at a US base in Khost province, killing seven CIA agents and a Jordanian Intelligence official.

More details are emerging about al-Balawi's life, including how he went by the name of Humam Khalil Mohammed, and how he assumed the online persona of Abu Dujana al-Khorasani - an outspoken opponent of US operations in Iraq and Afghanistan who was described as one of the top five jihadists on the web.
